I have a split bi-level home with apartment on the side. (mother daughter set up) I had my roof replaced 5 years ago. This past few weeks notice water coming from ceiling. Went into attic on apartment side and all boards are wet, more so towards the edge of the roof and the ridge vent is full of water when pushed on. It rained around 2 weeks ago. But the attic on the main house is dry and fine. I need to know if roofer is responsible, what the problem is, and how best to get this fixed. PS i tried to upload image but kept getting error message. PLEASE HELP.
